DIY Automatic Motorized Paint Shaker! 

I appreciate that you set the timer to "P0:0P"

Noga. Hakko. Knipex. Clearly a man of taste. And did I see Wiha? I couldn't tell. If only there were affiliate links...

Obviously you spent more time designing and fabricating this shaker setup than the amount of time you would have spent shaking cans. And I like it. I think you also like doing such things more as a challenge that anything else. And there is nothing wrong with doing that either. I actually see me in such doings... Thumbs Up to your design efforts and never having non-properly shaken spray paint cans ever again!

My main takeaway from this is that i am going to build my own can shaker - seems fairly simple :) thanks

I made one of these for my reciprocating saw, it works great and it was built from scrap materials.

3" Hole saw + something to wedge the can to one side. Works great, takes 3 seconds to load, and I always have it with me. That said, I want one of these.

I use a 10" x 3" PVC tube with a cap and a bolt chucked up in my drill. Drop the Spray can in and spin for 15sec each end of can. Work great.

I half expected the weight of the motor and the electronics just floating in the air to be a problem, but it seems to run fine. Nice job.

Just a sanity heads up if you put your cans into warm/hot water for a few minutes before use you dont have to spend minutes shaking the cans just 15 seconds when warm and they are properly agitated unless its undercoat and it will need 30 seconds. Bonus is the warm paint and the warmed butane driving it will perform significantly better.

I like this idea a lot.

amazing! ty for the files!

Making your way to the top step by step

What a great project......

Great video

This is a really cool project. Good job!

Tape the paint can on a saws all,and go,pretty slick 👌

great solution for a lot of things!

Love it!!!

Awesome build!

Awesome as always!!!!!!!!

Awesome project! 👍🏼👍🏼

Nice project! I need to make this for mixing my resin for the 3D Printers👌🏻🤓

Nicely done! Kind of a conincidence. I left my pla 3d printed drill paint can shaker outside and the cold made the plastic brittle. So now I have to print another. Side note thank you for the information on the k1. You were spot on. I bought and replaced the original extruder and now she is a good one!

I actually made one out of an old hedge trimmer about 10 years ago still use it to this day. I use a timer from an old toaster oven to control how long it shakes the can. it wasn't all that hard to make I sent pictures of it in action to one of those patent companies they told me it was not feasible to make and that it probably wouldn't sell anyhow looks like they were wrong or they stole my idea .

It looks like the electronics probly experience significant vibration, that could be an issue. The timer isn't built for that, so I expect cracked solder joints causing random shut downs or restarts.

as an alternative to machinging the hex shaft, you could get a driver bit with a slimmer shaft. it would be 1/4" on the drive end, but the business end would be thinner.

I knew about those blue/light grey deburing tool but didn’t know they had other insert to deburring external chamfer!

Attach a glass jar to it and put a bulb of garlic in the jar. If it's vigourous enough it will have the effect of peeling the garlic gloves. I do it by hand, but I've also wanted to make a electric gadget for the kitchen to do it. This would work. Overkill, but fun.

Just found your channel and Subscribed. Very nice work

Finally a solution to a problem no one knew existed 🙂

love it........ thanks for putting this on printables....great stuff...i really thought you were going to cnc this out of aluminum :)

Nice. I have one I built 20 years ago from a copier. It’s over kill I could shake a car with it but the lesson I learned was shake the can like your arm would. Slowly. The short fast stroke you have will shake the straw out of the nozzle in the can. Slow yours down.

We need some details on the chop saw mods!

You should make a spring hook setup to retain the can. Tooless operation that way.

Nice solution. I do wonder if a soft start/stop would be feasable.

Robert I always love your projects. Thanks! I use a rattle can shaker that goes in a recip saw. Absolutely love it!

Very cool project! What are those things in the red pouch? Why the thick walls on the timer housing? I always flip my spray cans upside down to shake. The assumption is they've been sitting right side up since they were filled, so all the solids have settled to the bottom.

Great idea! I need to build one. Any concerns covering up the motor cooling holes?

Interesting project. I wonder if a Velcro strap would hold the paint can to the machine, seems like extra work to screw and unscrew that hose clamp.

Great idea but I'm just wondering if you could simplify the design by moving the motor forwards on to the main frame and mounting a new flywheel directly to the motor shaft.

Amazing project. Will velcro work to secure the can? Or a large reusable ziptie?

Beautiful. Reduce shake speed for effective shake

Fantastic project and I really want one. BUT, I'm not spending that much to shake a can. 😧

how can i make the little chop saw for the hex shaft? it's so cool!

maybe an insulated cover you can drop over it to catch any accidental spills and keep the noise down.

Thanks for the great little project! 👍

I just don’t shake the cans and have bad paint jobs. Very simple and quick. “Painters HATE this one weird trick!”

Need to make your printable parts purchable !!

I made a bracket that attaches a paint can to my saws all

Now I want a fully 3D printed shaker that doesn't require and seatbelt tightening mechanism. Maybe a friction compliant mechanism to just insert depressing a button and delaying motivation for ~5 seconds

Just wondering why you didn't buy a hex to 6mm (guestimate?) coupler rather than turn down the hex shaft to round.

Wouldn't a lab roller mixer like they use for resins also do its job?

Nice build and video! However I'm wondering if using a paint shaker would really offer better spray quality than just shaking by hand 🤔 Interested in seeing a short video comparing hand-shaken vs the machine and see the finished surface, then we can all learn something in the end!

neodymium magnets would be a nice up grade no annoying clamp!

Neet way to mix paint. But it’s a bit complicated. I use a heavy duty succion cup and a drill. I stick it below the can, not quite in the center, and spin the thing. For piece of mind I put my drill on the hammer drill setting. I’d hate to be the paint inside the can.

I really like the use of heat thread inserts here: no nuts to lose if you decide to remove the motor for more compact storage later and the PETG will probably keep the screw under a bit of tension so less likely to vibrate loose but with locktite it's just not going anywhere. Also making the motor mount out of PETG along with the compliance in the coupling would along with better longevity of the plastic maybe give some dampening properties to the motor and the electronics box. Not sure if that's going to make any tangible difference in keeping all the solder joints or the brushes inside the motor intact but it's probably better than a full hard mount. 11:29 I think this is a very valuable feature, ergonomics are pretty important and the ability to adjust the screen so it's clearly legible without having to bow down or twist your head in weird angles is going to make this a lot more approachable to use. I guess after using it a couple of times all you need is to blindly press the start button and not look at the display but even for just aesthetics reasons I really like the decision to make it pivotable.

Any sense in expanding it to do 3-4 cans at once? Is it possible, feasible and worthwhile to try that?

Great video. Did you post the link to printables for 3d parts ? I don't see it

Would the plastic actually break without the long bolts? In my experience PETG is terrible in high vibration situations. I've tried it for motorcycle parts too, it sucks. PLA works way better than people seem to think It surprises me too when I do a throw-away PLA prototype and it ends up lasting years and years of torture.

Robert - that is a really cool functional project. I also liked the notches in the sides of the case to facilitate removing the display. Nice extra touch from an experienced designer 👍👍😎👍👍. Quick - question.... Did you need to print the case with supports on the internal cavity, or was the span small enough to bridge across the gap knowing the surface finish was going to be hidden?

Great video, thanks a lot. I ordered the same relay but for the life of me can’t figure out the wiring. Can you elaborate and help a guy out? Thanks!

Awesome! But could you please adjust the usage of the word "so"? Please?

Wonder if a grease gun clamp would be good as a quick release for paint can?

I tape a can or two to a long Sawzall blade and run it on the oscillating mode, shakes the living daylights out of a rattle can.

That mini cutter is interesting. I see it being sold on aliexpress but not powered from DC, so I assume motor was replaced with something better.

When running, there seems to be a lot of wiggling of the motor and 3D printed bracket. Perhaps the 3D bracket should have had a 3rd arm to make it more rigid?

A plumbers expansion plug and hunk of PVC turns any electric drill into a paint shaker in seconds, but this is still interesting.

Can I buy that mixer with you? Thanks

Could also be a martini shaker, or a hoo hah rattler... :-P

That is how the shaker should have came

Thumb screw would be great on that hose clamp full tool less design then

Take sawzall with long blade and attach a can of paint using duck tape to it. You are welcome.

1/4 hex you could have used an old 2in Phillips bit

I dunno man, 450rpms doesn't seem too fast to me- time for high-speed testing with BL motors... :D

I just give the can to my kids and tell them “I bet you’re not strong enough to shake this can for two whole minutes” then I have a shaken can in two minutes

3D print?

I'm sure it only says 300rpm to repress your freedumb

At close to $100 for all the parts, I guess I'll stick to the "natural motion" of my male hand to shake my spray cans. ;-)

What will it do with a can of beer?

You can literally just weld the tang end of a thick sawzall blade to a cheapo quick clamp. Spray paint goes into the clamp and the clamp goes into your sawzall. Follow me for more recipes.

Great final product but I'd hate to listen to that for 5 min. Haha

“It doesn’t really work like that “?

Sawzall works as well 😂

Shaken but not stirred...

Dude. Make these for nut butter.

Dude just tape the can onto a saw saw blade and use it on the sawsaw

Some of the best projects happen due to being lazy

Do not try this at home; I routinely take my aerosol spray paint cans and put them in my heated ultrasonic cleaner. Heat and shake at the same time. I just take them out and shake them for 10 seconds or so and I'm ready to go.

why you Americans overreact about everything? 5m shaking in motorized shaker? come on... i take the spray can from the shelf and shake it by hand till i reach the place where i want to spray, its enough...

No need for something like that around here just hand it to a local meth head .i seen a can shook so hard you could see ball dents from inside out i would never have believed it if i hadn't seen it with my own eyes

IT SAYS POOP

Utterly laughable! Why not ADD a Raspberry Pi to flash an LED while the timer runs?

Not a good paint shaker at all, would not be mixed properly.

First

strange idea: dont use spray paint.

VanSickle is horrible paint. Stick with the bog standard Rustoleum.

IT IS NOT HARD TO SHAKE A PAINT CAN FOR 60 SECONDS.
